BABAR Computing System Home Page

The BABAR Computing System includes the following elements:

  • online (data acquisition, control, monitoring);
  • offline (CPU, network, storage);
  • software environment in which the computing work is done (including code development/management, user concerns, distributed computing issues, etc.); and the
  •  collaboration code itself (on-line, reconstruction, simulation, etc.).

This page is an entry point for more information about this system.
